DIC_ROCK_ALL (3677 rows)
Dictionary table based on the entire version 3 of the BGS Rock Classification Scheme and is populated directly from the 3 supplying tables (BGS.ROCK_NAME_V3, BGS.ROCK_COMPOSITE and BGS.DIC_ROCK_DUMMY). It contains both the base rock names and addditional codes required for specific application, eg. composite names for use on digital geological maps. It is formally approved as the official source of ALL database codes to be used in BGS corporate databases and MUST be followed.

28	+#~IR	RN	Meta-igneous rock - In the Rock Classification Scheme, a rock is classified within this category if it is considered to be a metamorphic rock derived from an igneous protolith, either because of its lithological characteristics (i.e. preservation of igneous textures and in some cases composition or mineralogy) or its lithological associations. The class includes meta-igneous rock based on protolith name, meta-igneous rock based on modal composition, and meta-igneous rock based on textural attributes. British Geological Survey Research Report RR/99/02, section 5 and fig. 1.	Meta-igneous rock	C	AWEL	08-MAR-00	TMCM	22-FEB-19	A
29	+#~MOD	RN	Meta-igneous rock based on modal composition - In the Rock Classification Scheme, a meta-igneous rock is classified within this category if it cannot be classified according to protolith name. The class includes metafelsic-rock, metamafic-rock, and meta-ultramafic-rock. They are distinguished on the relative proportions of quartz, feldspar, and mafic minerals. Muscovite, carbonate and other generally pale-toned minerals are considered neutral and not used in the modal classification.

30	+#~TEX	RN	Meta-igneous rock based on textural attributes - In the Rock Classification Scheme, a meta-igneous rock is classified within this category if neither the exact nature of the protolith nor the modal composition is known. This class includes orthoschist, orthogneiss, and orthogranofels. British Geological Survey Research Report RR/99/02, section 5.3 and fig. 1.

31	+*CSSR	RN	Carbonate sediment and sedimentary rock - In the Rock Classification Scheme, carbonate sediments and rocks are defined as rocks in which the carbonate component forms more than 50% of the sediment or rock. For a rock to be termed a carbonate sedimentary rock, the 50% carbonate criterion should not include any carbonate cement in an originally non-carbonate rock. The class is divided into lime-sediment and limestone, dolomite-sediment, dolostone and magnesite-stone, and Na carbonate sedimentary rock, defined on the basis of the carbonate composition. British Geological Survey Research Report RR/99/03, section 3.	Carbonate sediment and sedimentary rock	C	AWEL	08-MAR-00	TMCM	08-MAR-19	A
32	+*DSRM	RN	Dolomite-sediment, dolostone and magnesite-stone - In the Rock Classification Scheme, these are defined as carbonate sediments and sedimentary rocks which are dominantly (> 50%) composed of a magnesium carbonate in the form of dolomite (CaMg(CO₃)₂), ankerite (Ca₃ (Mg₂Fe) (CO₃)₆) or magnesite (MgCO₃.

37	+*NCSS	RN	Non-clastic siliceous sediment and sedimentary rock - In the Rock Classification Scheme, these are rocks and sediments which are composed of more than 50% silica of biogenic or chemical origin. The classification is based upon the stage of the mineralogical transformation of silica, the type of silica and, if recognisable, the type of biogenic matter.

38	+*PS&P	RN	Phosphate sediment and phosphorite - In the Rock Classification Scheme, these are defined as those sediments and sedimentary rocks which have more than 50% phosphate minerals. These may be phosphates of calcium, aluminium or iron (equivalent to about 18 to 21% wt P₂O₅ depending on the nature of the phosphate minerals present).
